TI  - Microsphere-Assisted Robust Epidermal Strain Gauge for Static and Dynamic Gesture 
      Recognition.

AB  - A novel and robust epidermal strain gauge by using 3D microsphere arrays to 
      immobilize, connect, and protect a multiwalled carbon nanotubes (MWNTs) pathway 
      is presented. During the solvent deposition process, MWNTs sedimentate, 
      self-assemble, and wrap onto surface of polystyrene (PS) microspheres to 
      construct conductive networks, which further obtain excellent stretchability of 
      100% by combining with commercially used elastomer. Benefiting from its 3D 
      conductive pathway defined by microspheres, immobilized MWNT (I-MWNT) network can 
      be directly used in practical occasions without further packaging and is proved 
      by tape tests to be capable of defend mechanical damage effectively from external 
      environment. By parameter optimization, the strain sensor with 3 microm PS spheres 
      obtains stable resistive responses for more than 1000 times, and maintains its 
      gauge factor (GF) of 1.35. This thin-film conductive membrane built by this 
      effective construction method can be easily attached onto fingers of both robot 
      and human, and is demonstrated in sensitive epidermal strain sensing and 
      recognizing different hand gestures effectively, in static and dynamic modes, 
      respectively.
